I've installed a Ubuntu 12.04 with Windows 7. At the very beginning it worked perfectly and raised no problems. I installed the 3rd party updates also while installing the OS. So the MP3 and videos are working perfectly.
But a day later, a big core problem is raised on my system. If I opened the Ubuntu Software-Center, it just opens and the animated wheel turns for a couple of second and suddenly it closes.
Likewise, all the LibreOffice applications are seeming so. When I open them, it just opens and welcome screen stands for a couple of seconds and suddenly closes.
I tried to overcome these issues by using these codes.
sudo rm /var/lib/apt/lists/* -vf sudo apt-get autoclean sudo apt-get update
And tried many codes. But nothing responds.
Hope my packages are crashed. So please anyone help me to overcome this issue Thank you
